PUMP-OPERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 425,216, dated April 8, 1890.

Application filed December 12, 1888. $crial No. 293,328. (No model.)

To all whom, it may concern.-

Be it known that I, FRANK GooDrELLow, a citizen of the United States, residing at Plattsburg, in the county of Clark and State of Ohio, have invented certain new and useful ,Improvements in Pump-Operating Apparatus, of which the following is a specification,

reference being had therein to the accompan yin g drawings.

This invention relates to certain new and useful improvements in apparatus for operating pumps, and particularly pumps used for supplying water to animal drinking-troughs. v

avoid the manual labor of rewinding the chain or rope on the drum.

The invention consists of certain other details hereinafter more fully pointed out.

111 the accompanying drawings, forming a part of this specification and on which like reference-letters indicate corresponding parts, Figure 1 represents a side elevation of my improved apparatus; Fig. 2, an end view of the water-trough and an elevation of the platform and adjuncts with the operating-lever in section, and Fig. 3 a plan view of the apparatus.

Letters A, B, and O designate, respectively, a well, a pump, and a water-trough of ordinary construction, the pump and the trough being connected by a pipe D. Near these, and preferably between them, is placed my apparatus, the frame of which is designated by E, and is constructed, preferably, of wooden beams. In it is mounted a train of gearing F, G, H, and I.

At J, I mount a drum K, upon which is wound a driving sprocket-chain L, the flanges of the drum being preferably only sufficient-ly far apart to accommodate the width of the chain, so as to cause it to windin a continuous roll without shifting endwise, whereby it is prevented from liability to run off of the driving sprocket-wheel M, mounted on the shaft of the gear F The shaft 0 of the pinion I of the train has a crank connected by a pitman P with one end of a lever Q, f ulcrumed at R, and connected at its other end with the pump-piston by a link S, whereby the piston is actuated. This shaft 0 also carries a cam T, having an undulatory periphery, which engages with the upper' bifurcated end of the pendulum U to regulate the speed of the ap parat-us. The bifurcations of the pendulum carry anti-friction rollers V. The pendulum weight or ball is adjusted on the pendulum to vary its control of the speed of the cam. A pivoted detent X engages with the pinion I of the train and locks the apparatus against rotation whenever the water in the trough is high enough to support the float Y, which is connected to the detent by a stem Z. \Vhen the height of the water gets lower than is necessary for this purpose, the float descends and the detent is disengaged and the weight actuates the several gears and the pump.

The letter A designates a platform hinged at one end and resting at the other upon the drum-operating lever B, fulcrumed at C. The platform is further supported and returned to normal position by weights D, suspended by ropes E, connected to the platform and passing over the pulleys Gr, supported in posts 11. The longer arm of the lever carries a pawl I, which is directed into engagement with the ratchet J, carried bythe drum-shaft J by a spring K, as said end. of the lever moves upward, and is disengaged as the lever moves downward by contact with a lug L, carried by the frame, or otherwise, so that the pawl will not prevent the drum from rotating as the chain unwinds. It will be observed that as the animal steps upon the platform and moves toward the trough the platform will descend and operate the lever B and cause it to wind the chain more or less on the drum. The sprocket-wheel M is allowed to turn backward by means of the clutch-connection shown in Fig. 3. As shown in said figure, one end of the hub of the said wheel forms the rotating member of a clutch, while the non-rotating and sliding member is formed of the roller M, fitted over the spline 0 and held against the hub member by a spring P.

The weights D are sutiieicnt to prevent the platform from being forced violently down when the animal steps upon it.

It will be observed that my imgrovcd apparatus avoids the necessity of manual labor of winding the operating-chain upon the druma great advantage in practice-that any descent, however small, of the weight. rotates the operatingsproeket correspondingly without loss of motion, and that the apparatus is started and stopped automatically by the height of the water in the trough. The arrangement between the platform, the lever, and the drum will be such that each animal 1 will wind the chain sntiicient to pump about the average amount of water drank by each animal.

I do not wish to be understood as confining myself to the precise arrangement or details of construction shown and described, as it is perfectly obvious that the essentials of my invention may be secured irrespective of these particular forms.

llaving thus fully described my invention,

2 5 what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a pum i-operating apparatus, with a train of gem ing, a drum separately mounted upon said gearing and 0 having a ratchet-wheel, a sprocket-wheel on one of the gear-shafts, clutch devices to engage the shaft and sprocket-wheel in one direction and disengage them in the other, and devices for connection with the pump piston, of a pivoted platform, a pivoted lever, its pawl engaging with the drum ratchetwheel to r tate the drum by the depression of the platform when the animal steps upon it, and a weighted rope or chain wound on said drum and passing over said sprocketwheel. I

i. The combination, in a pum 'i-operating apparatus, with a pivoted platform, sheaves mounted near to it, ropes connected to the platform and passing over the sheaves, and weights connected to the ropes to control the depression of the platform when the animal steps upon it and to return it to normal position, of a pivoted lever one arm of which is engaged by said platform, a pawl carried by the other end, a drum carrying a ratchetwhcel, with which said pawl engages and disengages with the up and down movement of the lever, a weighted rope or chain wound upon said drum, and a train of gearing with which said rope or chain engages.

In testimony whereof I allix my signature in presence of two witnesses.
